Molecular bricklaying: the protonated benzimidazole moiety as a synthon for crystal engineering

Matthews, Craig; Broughton, Vanessa; Bernardinelli, Gerald; Melich, Xavier; Brand, Guy; Willis, Anthony; Williams, Brook

Description

The crystal structures of three salts of diprotonated 1,2-bis(1H-benzimidazol-2-yl)ethane, 1, with tetrahalogenometallates are reported. The crystal lattices are constructed from two types of interactions, the stacking of the protonated benzimidazole groups and N-H⋯Cl hydrogen bonding between the cations and the complex anions. Depending on the conformation of the cation, two- or three-dimensionally stacked structures are formed. A similar packing motif is found with the related cation formed...[Show more]
